Device Control Instruction
Device control instructions are used to determine the communication sequence between the PNC-1050 and
computer through RS-232C interface and/or tell the PNC-1050 the current computer state. among them, some
device control instructions set the output specifications of mode 2 instructions.
Each device control instruction is organized with three letters: ESC (1Bh), “.” and one uppercase letter. Device
control instructions are of two types: one with parameters and the other without parameters.
Parameters can be omitted. A semicolon “;” is used as a delimiter to separate parameters if they are input in
succession. A “;” without parameters means that parameters were omitted.
If parameters are omitted, the default value is set. For a device control instruction with parameters, a terminator
needs to be input in order to signify the end of instructions. A colon “:” is used as the terminator which cannot be
omitted.
